(Java) setBounds issue with a JLabel
Question
Ill keep this brief, because all im simply asking is for a line of code. Heres my problem, so in order for my Jlabel to show up i Use .setBounds
My problem is I cannot guess the width of my text so what would i need to do in order for my setBounds to take the Width and Height as the text is.
If i have not explained this very well do say and ill try and explain more.
Some1 wanted an example so here goes:
My Code Snippet:
JLabel poisonDescription = new JLabel("This is the poison icon, when this appears...");
//My declaration.. the next is inside a void.
poisonDescription.setBounds(50, 50, 400, 20);
add(poisonDescription);
its pretty simple, i want the Bounds to resize to the size of the font!
Oh yeah another question... How do i make a JLabel multi line?

Don't use setBounds, simply leave the JLabel handle himself its preferredSize. Whatever Layout you choose for the label container, it will handle the label properly.
To have a multiline label, simply use a JTextArea:
JTextArea textArea = new JTextArea();
textArea.setEditable(false);
textArea.setLineWrap(true);
textArea.setOpaque(false);
textArea.setWrapStyleWord(false);

You can use HTML for do it.
import javax.swing.JLabel;
import javax.swing.JOptionPane;
public class Main {
public static void main(String[] args) {
JLabel label = new JLabel("<html>One<br>Two!");
JOptionPane.showMessageDialog(null, label);
}
}
For more details, see in How to Use HTML in Swing Components in The Java Tutorial

The answer to your main question is this is the problem that LayoutManagers were designed to fix. If you want to fix this problem, stop using a null layout, start using a simple layout manager like FlowLayout or BorderLayout and let the layoutmanager size your label
For question #2 about multiline labels, the easiest way is to pass in properly formatted HTML with <HTML> tag included

l1 = new JLabel("UserName");
l2 = new JLabel("Password");
t1 = new JTextField();
t2 = new JTextField();
b1 = new JButton("Log In");
b2 = new JButton("Cancel");
l1.setBounds(100,100,40,30);
l2.setBounds(100,150,70,30);
t1.setBounds(200,100,150,30);
t2.setBounds(200,150,150,30);
b1.setBounds(100,200,90,30);
b2.setBounds(200,200,90,40);
simply you can provide the dimensions for button textfield and others ...
